Connect and directly driven by the 6th servomotor by the 5th servomotor drive, the second left roller shaft.

2. three rove list ingots are controlled or unify a controlled feeding Yarn spinning method, it is characterized in that: during spinning, and pressure-applying unit is depressed, Closely pressing between back cot and the left roller set of rear roller, middle roller set and right roller are overlapped, mid-rubber roll and middle roller it Between closely pressing, closely press between front rubber roll and front roller, the first rove by back cot and left roller overlap between pressing feeding, Second rove by back cot and middle roller overlap between pressing feeding, the 3rd rove by back cot and right roller overlap between pressing feed Entering, the right-hand member of the roller shaft of the single-ingot spinning device of the rightmost side stretches out the right-hand member of the 3rd middle roller axle by the first servomotor band Dynamic, middle roller is driven by the second servomotor, and front roller is driven by mair motor；When the structure of each single-ingot spinning device is identical Time, the first Serve Motor Control roller shaft rotates, and then realizes the unified of the first rove to all single-ingot spinning devices and feeds Control, if the first middle roller axle of each single-ingot spinning device is all connected by the first belt and the first power transmission shaft, the 3rd servo Driven by motor the first drive axis, then drives the rotation of the first middle roller axle of all single-ingot spinning devices, then drives The rotation of the middle roller set of all single-ingot spinning devices, the unification then realizing the second rove to all single-ingot spinning devices is fed Entering to control, if the first right roller shaft of each single-ingot spinning device is all connected with second driving shaft by the second belt, the 4th watches Take driven by motor second driving shaft to rotate, then drive the rotation of the first right roller shaft of all single-ingot spinning devices, then carry The rotation of the right roller set of dynamic all single-ingot spinning devices, realizes the unification of the 3rd rove to all single-ingot spinning devices then Feeding controls, if the first middle roller axle of certain single-ingot spinning device is directly individually driven by the 5th servomotor, first right sieve Pulling shaft is directly individually driven by the 6th servomotor, then drives middle roller set, right roller set to rotate, then realizes this list ingot Second rove of spinning apparatus, the 3rd rove be fed separately into control；When the left side list ingot that each single-ingot spinning device is adjacent When spinning apparatus or right side single-ingot spinning device become axial symmetry to arrange about both center vertical straight line, the first servomotor control Roller shaft processed rotates, and then realizes the 3rd thick of the first rove to all of left single-ingot spinning device and right single-ingot spinning device The unified feeding of yarn controls, if the second middle roller axle of each left single-ingot spinning device is connected by the first belt and the first power transmission shaft Connect, the first power transmission shaft is driven by the 3rd servomotor, then drive all left single-ingot spinning devices the second middle roller axle turn Dynamic, the rotation then driving the middle roller of all left single-ingot spinning devices to overlap, then realize all left single-ingot spinning devices The unified feeding of the second rove controls, if the second right roller shaft of each left single-ingot spinning device is passed by the second belt and second Moving axis connects, second driving shaft is driven by the 4th servomotor, then drives the second right roller of all left single-ingot spinning devices The rotation of axle, the rotation then driving the right roller of all left single-ingot spinning devices to overlap, then realize all left single-ingot spinnings The unified feeding of the 3rd rove of device controls, if the 3rd middle roller axle of each right single-ingot spinning device by the first belt with First power transmission shaft connects, the first power transmission shaft is driven by the 3rd servomotor, then drives middle sieve of all right single-ingot spinning devices The rotation helped pull a cart, the unified feeding then realizing the second rove to all right single-ingot spinning devices controls, if each right single ingot Second left roller shaft of spinning apparatus is connected with second driving shaft by the second belt, second driving shaft is by the 4th servomotor band Dynamic, the rotation then driving the left roller of all right single-ingot spinning devices to overlap, then realize all right single-ingot spinning devices The unified feeding of the first rove controls, if the second middle roller axle of certain left single-ingot spinning device is directly by the 5th servomotor list Solely drive, the second right roller shaft is directly individually driven by the 6th servomotor, then drives middle roller set, right roller set to rotate, Then realize the second rove to this left single-ingot spinning device, the 3rd rove be fed separately into control, if certain right single-ingot spinning 3rd middle roller axle of device is directly individually driven by the 5th servomotor, the second left roller shaft is directly by the 6th servomotor list Solely drive, then drive middle roller set, left roller set to rotate, then realize the second rove to this right single-ingot spinning device, the One rove be fed separately into control；Feeding rove in succession by rear roller drawing-off to and middle roller drawing-off to composition first break draft The drawing-off effect in district and middle roller drawing-off to and the front roller drawing-off drawing-off effect to the front draft zone of composition, after obtaining drawing-off Yarn.
